From a PayScale survey, here are the most highly recommended jobs in America(click through to get to the highest recommended job): Software product manager
Recommended: 90%
Median salary: $93,000
Projected job growth: 15.3%

That's the question salary data provider PayScale posed for the first time to over 10,000 workers in its annual Best Jobs For You survey. The survey also asks about job satisfaction, flexibility, and whether respondents felt their careers had meaning.

Of the roughly 200 jobs examined, optician is the only profession that garners a 100% recommendation rate. Comparatively, the next top-recommended jobs have a 94% rate.

Surprisingly, pay does not seem to be the top factor in a job's high recommendation rate. Opticians make a median salary of $34,100 a year, and the highest earners in the profession make less than $55,000, according to the U.S. Bureau of Labor Statistics. On the other hand, sales VPs, which doesn't make the top 10, earn $148,100 per year — but only 82% say they would recommend the job to a friend.

So what's so great about being an optician? According to PayScale's lead economist Katie Bardaro, 75% of opticians report being fairly or extremely satisfied with their jobs (compared to an average of about 70%), and it was listed on the U.S. News & World Report 100 Best Jobs list for 2014. Perks of the job include below average stress and above average upward mobility and flexibility.

On the flip side, the least recommended jobs in America include cashiers, bank tellers, and truck drivers, which have recommendation rates of under 30%.
